To all whom it may concern:

Be itknown that I, EDWARD E. ALLEN, a citizen of the United States,residing at Erie, in the county of Erie and .State of Pennsylvania, haveinvented new and useful Improvements in a Vulcanizing Press, of

which the following is a specification.

This invention is particularly designed for use with vulcanizing presseswhich have a vulcanizing chamber of considerable length which isprovided with a ram adapted to traverse the chamber so'that a largenumber of tires may be vulcanized in one opera- The ram in such avulcanizing chamber is usually actuated by a hydraulic lift, the pistonextending from the hydraulic cylinder into the vulcanizer. The mountingof the vulcanizing, chamber is one of some ditticulty because of thestrain to which it subjected and the necessity for alining the chamberwith the piston. The present invention is directed to theconnectionbetween the vulcanizing chamber and the hydraulic cylinder by means ofwhich the mounting for the chamber is improved.

The invention is'illustrated in the accompanying drawings :wherein Fig.'1 shows ve'rticalgcentral section of the device. f

Fig. 2 a plan view of the-base. Fig. 3 a bottom view of the head. of thevulcanizing chamber.

1 marks the head of the vulcanizing cham her, and 2 the shell of thevulcanizing chamher. This shellis commonly formed of steel andrivetedito the headl. A ram 3 operates in the vulcanizing chamber and isactuated by a piston .4 with sutlicient travel to carry the ram to thetop of the chamber. piston 1: extends from the plunger 5.' The plunger 5operates in a hydraulic cylinder 6. The base 7 is carried ordinarily bya concrete bed 8 having a pit or well 9 into. which the cylinder 6extends, the cylinder being hung or suspended from the base 7. Thepiston extends through the usual glands 10 and 11 on the head and baserespectively. these glands making a steamtight and water-tight jointrespectively. The base has the ribs 12 extending to post supports 13.The post supports have perforations extending through them and the postsl iextend through these perforations, the posts having shoulders 15resting on the supports Nuts 16 are screwed on to the Specification ofLetters Patent.

lower ends of the posts so as to securely clamp them in place. The head1 is spaced from the base 7. The head 1 has the ears 1? extending fromit, these ears being pro vided with perforations 18 through which theposts extend. The posts are screwthreaded and provided with the nuts 19which form adjustable shoulders on which the head rests. By adjustingthe nuts 19 the shell 2 can be alined with the piston so that the ramwill travel with equal clearance throughout the length of the shell.This is of importance because the shell is ordinarily made of steel andriveted to the head 1 and it is,theretore, very difficult to get theshell inexact alinement with the head even though the head may be turnedaccurately. By means of the adjusting nuts 19 any in accuracy may be,corrected. The nuts are locked in adjustment by the jam nuts 20' and thehead is clamped on the shoulder 19 chamber are mounted; a rain in thevulcanizing chamber; a piston extending from the ram through the headand base; and a series of posts each detachably and separately securedto the head and base and supporting the vulcanizing chamber.

2. In a vulr-anizing press, the combination of a vulcanizing chamberhaving a bottom head; a hydraulic chamber in alinement' with thevulcanizing chamber; a base on which the hydraulic chamber andvulcanizing chamber are mounted; a ram in the vulcanizing chamber; apiston extendingfrom the ram through the head and base; a series ofposts secured to the ,head'and base and supporting the vulcanizingchamber; and means for adjusting the posts to aline the vulcanizingchamber.

3. In a vulcanizing press, the combination of a vulcanizing chamberhaving a bottom head; a hydraulic chamber in alinement with thevulcanizing chamber; a base on which the hydraulic chamber andvulcanizing chamber are mounted; a ram in the vulcani /iing; chamber; apiston extending from the ram through the head and-base;

and a series of posts secured to the heada head; a shell secured to thehead and ex tending therefrom; a hydraulic cylinder; :1

base onwhieh the cylinder is mounted, said base having perforated post,supports; shouldered posts resting on the supports;

perforated projections on thehe'ad throughwhich. the posts extend; nutsscrewed on to the posts on which the projections rest; and 'nutsarranged above the pro ect1ons for clamping the projections onthe'posts.

In testimony whereof I-have hereunto set my hand.

EDWARD IE. ALLEN.
